摘要
给出一种构建和管理异构模式之间转换的方法。重点给出关系模型到Web环境下多使用的层次模型的数据交换。交换从源模式和目标模式的语义出发,包括语义转换和数据转换两个阶段。
The way to transform between heterogeneous schemas is presented. The translation from relational model to hierarchical model, which is commonly available on the Web, is mainly discussed. The translation is based on the semantic of source schema and target schema, and includes two phases： semantic translation and data translation.
